1988 Gmc C2500 pickup problems
The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2002 model years, this is the final generation of the C/K model line. In a branding change, GMC adopted the GMC Sierra nameplate for all its full-size pickup trucks, leaving the C/K nomenclature exclusive to Chevrolet.
Internally codenamed the GMT400 platform, GM did not give the model line a word moniker (e.g., "Rounded-Line series" for its predecessor). After its production, the model line would informally become known by the public as the "OBS" (Old Body Style), in reference to its GMT800 successor. In starting a different tradition, the model line overlapped production with both its predecessor and successor; the model line again shared body commonality with GM medium-duty commercial trucks.
Over nearly a 14-year production run, the fourth-generation C/K was assembled by GM in multiple facilities in the United States, Canada, and Mexico. After the 2000 model year, the fourth-generation C/K was discontinued and was replaced by the GMT800 platform (introduced for 1999); the C3500HD heavy-duty chassis cab model remained in production through 2002. In line with the GMC Sierra, Chevrolet subsequently adopted a singular Chevrolet Silverado nameplate for its full-size truck line (which remains in use).

Common 1988 Gmc C2500 pickup problems
Based on the search results, here are some common problems with the GMC C2500 pickup 1988:
- Coolant Leaks or Oil Leaks from Intake Manifold Gaskets: The intake manifold gaskets in 1988 and 1998 GMC C2500 pickup trucks may develop external engine oil or coolant leaks. These vehicles may also develop internal coolant leaks that cause coolant to mix with the engine oil, which can damage the engine. This problem most often occurs at around 175,000 miles. Fix this problem by replacing the intake manifold gasket, which will most likely cost somewhere between $300 and $450.
- Front Wheel Speed Sensor Failure: The front wheel speed sensors or anti-lock brake system (ABS) sensors may fail, causing the ABS warning light to turn on or the ABS to activate erratically. Many users report that the ABS activates on dry roads at slow speeds. This issue may cause the engine to stall or run roughly. Replace the faulty sensor to correct this problem.
- Excessive Oil Consumption: One of the most common 2007-2013 GMC and Chevy truck problems owners experience is excessive oil consumption. This issue may occur due to worn piston rings or cylinder walls, and it may cause the engine to run rough or stall. Replace the worn-out parts to correct this problem.
- Alternator Failure: In older Sierras and Silverados, the alternator may eventually fail, causing the battery to die and, possibly, an abnormal noise to occur. This problem may or may not cause a dash warning light to come on. If your alternator fails, you will need to replace it, which typically costs around $300 to $400. This problem occurs on average at around 125,000 miles.
- Internal Distributor Faults: Numerous drivers have reported that their truck developed internal faults in the distributor, although this problem isn’t as common as some of the others on this list. You may hear a squealing noise coming from the distributor, and the issue may cause the engine to run roughly or stall. The check engine light may or may not come on. You’ll need to overhaul or replace the internal distributor to correct this problem. Start watching out for internal distributor fault issues at around 130,000 miles.
- Failed Steering Wheel Position Sensor: If you get a service stability message in your Silverado or Sierra, it may be because of a failed steering wheel position sensor. These errors may occur intermittently or more regularly, such as every time you start your truck or turn the wheel. Replacing the sensor, which will cost you about $200 to $300, should fix this issue. This issue could occur at any time, but the average mileage at which it occurs is around 90,000.
- Failed 4WD Transfer Case Encoder Motor Position Sensors or Selector Switches: 1999-2007 Chevy Silverados and GMC Sierras are also known to experience some of the same common issues 2007-2013 models do. These include failed 4WD transfer case encoder motor position sensors or selector switches, failed HVAC temperature or delivery mode door actuators, and failed fuel level sensors.
- Fuel Pump Issues: The fuel pump may fail, causing the engine to stall or run roughly. Replace the faulty fuel pump to correct this problem.
- Ignition Module Failure: The ignition module in the distributor may fail, causing the engine to stall or run roughly. This problem may occur due to heat or wiring issues. Replace the faulty ignition module to correct this problem.
